The U.S. Green Building Council (USGBC) has released its annual list of the top 10 states for new LEED certifications in 2012, highlighting those regions that are transforming buildings and communities across the country.
The per-capita list is based on 2010 U.S. Census data and includes commercial and institutional buildings certified under LEED, through which approximately 2.2 billion sf has been certified worldwide through 2012.
"Securing a spot on this list is a remarkable achievement for everyone involved in the green building movement in these states," said Rick Fedrizzi, president, CEO and founding chair, USGBC. "From architects and designers to local chapter advocates, their collective efforts have brought sustainable building design and use to the forefront of the national discussion on the environment, and I applaud their efforts to create a healthier present and future for the people of their states."
Once again, the District of Columbia tops the ranking, with 36.97 sf of LEED space certified per resident in 2012.
Meanwhile, Virginia moved into position as the top state, with 3.71 sf certified per resident in 2012, overtaking Colorado, with 2.10 sf certified per person.
Other top states include Massachusetts, which moved up three positions from 2011, with 2.05 sf per person; Illinois, with 1.94 sf; and Maryland, with 1.90 sf of LEED space certified per resident in 2012.
Reflecting the ongoing trend of LEED existing buildings outpacing their newly built counterparts, in 2012 the LEED for Existing Buildings: Operations & Maintenance rating system accounted for 53% of total sf certified in these states, compared to 32% certified under LEED for New Construction.
The full ranking, which includes 10 states plus Washington, D.C., is as follows:
